w IMPROVEMENT IN ROTARY sPADERs.

The Schedule referred to in these Letters Patent and making part of the same.

To all who/m lit may concern Be it known that I, JAMEs Cnnn'owurrhof Shelbyville, in the county of Shelby and State of Mis souri, have invented certain new and useful Im provements in Rotary Spaders; and I do hereby dec-lare the following to be a full and exact description of the -same, reference being had to the accompanying drawings, in which- Fgure l is a side elevation of the spader complete.

Figure 2 is a plan view of the same.

Figures 3, 4, and 5 are detail sectional views of parts, hereinafter more fully described.

The object of this invention is to provide a machine which, in traversing the soil, will raise and turn over the same; and

It consists in the provision of one or more tractionwheels, provided with spades, automatically operated by means hereinafter fully specied.

I have illustrated two traction-wheels, provided with spades, but it is obvious that I may employ'a lesser or greater number, and that the spirit of my iuvention will be preserved, although but one or any larger number is employed.

A represents the frame;

B, the tongue;

C, a revolving colter; and

D, a bearing wheel.

E represents the traction-wheel, which is rmly secured to the axle E', journaled in the frame A.

F represents a cam, shown in perspective in iig. 5,

which is firmly secured to the frame A.

G represents shovels, secured by ball and socketjoint to the axle E', as seen at G', and whose handles pass through openings in the periphery of the wheel E, andthrough apertures in the slide G", which moves laterally in guides or ways on the inside of the periphery of said wheel.

The slide G" is provided on that end next the cam with two studs g g', which fit, one on each side of' the rim F of the cam F.

As the wheel E revolves, the studs g g' pass 'entirely around the cam, and retain the slide securely in the one position until the shovels leave the ground, when, owing to the departure which the cam takes at this point from a straight concentric line, the slide Gl is pushed over toward the other side of the wheel, and the shovels, consequently, caused to revolve. a quarter of a circle, and discharge their load.

The revolution of the shovel-handle being caused by the piu c, in the shovel-handle, coming in contact with the shoulder d on the wheel, as clearlyshown by dotted lines in iig. 4,

At this point the cam curves back to the line originally. taken, and the shovels are. automatically returned to condition for entering the soil.

When more than one whecl is used, I employ two distinct frames, united by a rod at the front, so that each frame may adapt itself to the inequalities of the surface without interfering with the operation of the other.

I also make one frame longer than the other, as clearly shown in iig. 2, whereby the soil discharged by the second wheel is thrown in the rear of the rst, and not against it, as would be the case were the two wheels in a line and upon the same axle.

-\Vhat I claim as my improvement, and desire to secure by Letters Patent, is-

1. The wheel E, spades G, ball and socket-joint G', and slide G, when combined and arranged as speciiied.

2. -Iu combination with the wheels E and spades G, the rotating c'olters G, as specified.

3. In combination with the elements ot' the iirstclaim, the cam F, when operating as and for the purpose specified. f
